摘要： The present invention is directed to a metering valve for controlling the amount of a fluid passed through the valve and a servo-valve for controlling the metering valve, wherein the servo-valve is decoupled from the metering valve to thermally distance or thermally isolate the servo-valve from any heat from the fluid passing through the metering valve. The metering valve and servo-valve may be used to attemperate a steam stream in a power plant attemperation system, such as a system for attemperating a superheated steam gas stream from a power plant being used for a heat-recovery steam generator. An integrated metering valve and discharge valve for discharging fluid during periods of non-use is also provide. Changeable throttle plates are also provided that control the flow of the fluid through the control chamber of the metering valve and the discharge valve.

摘要： The invention provides various designs of an apparatus and method for attemperating a gas stream temperature. The apparatus of the present invention provides a body through which a gas stream passes that permits, as desired, a second gas, such as gas outside of the gas duct or such as ambient air, to be added to the main gas stream to attemperate the temperature of the main gas stream. The body or device may be referred to as a variable eductor having a plurality of openings through which a second gas may pass into the main gas stream. The openings may be opened or closed, and the variable eductor provides control over which openings and the degree to which each opening is opened. In some designs the variable eductor is inserted between two portions of a gas duct. The variable eductor has widespread application, such as downstream of a gas turbine to attemperate the exhaust gas temperature during startup.

摘要： A method of eliminating dissimilar metal welds has been disclosed. The method includes the steps of providing a first part having a first alloy composition; providing a second part having a second alloy composition different from the first part; connecting a containment structure to the first part; pouring a powder into the containment structure such that the powder is in contact with the first part; positioning a portion of the second part in the containment structure such that the second part compresses the powder between the first and second parts; and performing hot isostatic pressing (HIP) to consolidate the powder and join the first and second parts together.
